TO ALL WHOM IT MAY CONCERN:

Be it known that I, lVILBIAM II. LIVINGSTON, of Johnstown, in the county of Fulton, and `State of New York, have invented, made, and applied to use a certain new andnseful Improvement in Saws; and I do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annex ed drawing, making part of this specification, whereini Figure l is a side elevation ofl my improved saw."

Figure '2 is a view of the tightening 'buckle edgewise of the saw.

Figure 3 is a section of the frame.

Figure 4 is a section, and

Figure 5 is a rear view of :1- modilication of the tightening-buckle.

Similar letters indicate the same parts.

rIhe framesaws generally used by butchers are made with a metal bach bent nearly at right angles at the handle, and inserted in a groove cutin the forward part of the handle, and there secured by rivets. This construction is costly, and the frame cannot be disconnected with facility from the handle in case saidhandle becomes broken or the frame requires hammering and straightening.

Thenatnre of my said invention consists in a metal frame passing into a hole in the handle so that it can be connected to or disconnected from the handleiwith facility, and a groove is provided in the upper edge of the handle, so as to prevent the handle turning upon the frame. And I employ a tightening-buckle that is attached to the lower edge of the handle and receives thescr'ew and nut that are employed for straining the saw.

In the drawing, a represents the handle, of any usual size or sha-pe; b is the saw, and c is they metal back, made of a round rod split at one end fo'rureceiving the saw and the cross-pin or rivet l. At the other end the rod c is bent at right angles, or nearly so, and inserted into the handle a, a hole being bored for tsseception, and I -stifi'en the rod a, by inserting the. plate c in a groove in the under side of said rod c, and securing the two together bypressing the metal of the rod c. down against the sides of the plate c. The handle is prevented freni turning around-upon the rod forming the back by the said rod c, or the plate c entering a groove in the upper edge of the handle. I employ a tightening-buckle, d, formed of metal, bent up at right angles, as seen in figs. 1 and 2, or solid, as seen in figs. 4 and 5, and in one side is a slot for the saw, as at 3, and at the other side is a hole at 4, for the screw i to pass through and receive the nut o by which the saw is strained. This tightening-buckle d is attached to the'lower edge of the handle, andI prefer thatit be alsoemployed to aid in holding the rod c into the handle, for which purpose I screwz the turningfbuckle itself, or its projecting hub upon the end of the rod c, and the screws 5 5 may be employed for more firmly attaching the tightening-buckle z'uto the handle a.

This mode of construction 1s cheap, light, and durable; no rivets are employed for attaching the back to the handle, and if required the handle can be taken off and another handle put on, or the back hammered or straightened if required. The round rod employed for the -back c is light' and stiff, and lesscns the cost'of manufacture. The slot at the forward end of the tightening-buckle prevents the saw being twisted when tightened.

What I claim, and desire to secure by Letters Patent, is-

1. Connecting the metallic back of a frame-saw to the handle, by passing the frame into a hole inthe handle, substantially as specified.

2. I' claim attaching the metallic tightening-buckled to the lower edge of the wooden-handle a, in the manner set forth. Y `I Y 3. I claim a metallic tightening-buckle formed with a slt for the reception of the end of the saw, a hole for the screw-rod and a nutA to screw upon the rod c, as set forth.A

4. I claimv the stiffener plate c', and the rod c, forming the frame of` the saw, as and for the purposes set forth. v

In witness whereof I have hereunto 'set my signature this 28th day of December, 1866.`

WM. LIVINGSTON.
